How to Learn Welsh with Comprehensible Input

Quick answer

Comprehensible input is Welsh you can mostly understand, with about one new word in every line. Spend your study time there, look up only the words that stop you, and move up a level when it starts to feel easy.

Many Welsh learners stall in the same place. They know the 29 letters of the Welsh alphabet and a long list of words, and they have learned the tables of mutations, the rules that change the first sound of a word, as when tad (father) becomes ei dad (his father) or ei thad (her father). They still cannot follow two friends chatting at a cafe. Tables and word lists don't turn into understanding on their own. Comprehensible input is the fix: you spend the same study time on Welsh where you already know almost every word, so the few new ones explain themselves.

What Comprehensible Input Looks Like

Each row below is a sentence. The gray bars are words you already know, and the purple bar is the one that is new.

Ideal Difficulty

About one new word per sentence.

At this difficulty you keep reading, because everything around the new word tells you what it means. You work it out yourself, and a word learned that way stays with you far longer than one memorized from a list.

Your Roadmap by Level

Bubblegum sorts every lesson into six levels, and each level is described by a sentence about the learner. Find the sentence that sounds like you, and the row tells you what to read and what to do.

  1. Level 1

    I'm just starting out or know only a few words.

    Read short dialogues that come with audio and a translation, and save the three words you look up most often. Duostories has free short Welsh stories with audio, written in North Welsh.

    Level 1 lessons about cafes and weekend plans
  2. Level 2

    I can handle simple exchanges.

    Read dialogues about everyday life with the translation hidden, and look up only the words that stop you. On YouTube, the S4C Dysgu Cymraeg channel posts short clips from S4C shows for learners, each labeled with its level, starting at Entry.

  3. Level 3

    I follow conversations on familiar topics.

    Read the week's big news stories on Lingo360, which lists the harder words for new speakers, and listen to each lesson once more without reading along.

  4. Level 4

    I understand most content but miss some nuance.

    Watch part of a show on S4C Clic with no subtitles, then with Welsh subtitles, and then with English ones to see how much you caught, as S4C suggests. Listen to Pigion, the BBC's monthly pick of Radio Cymru highlights for learners, which lists the harder words with their English meanings.

  5. Level 5

    I read complex topics but rare words slow me down.

    Read the news on Golwg360, which is written for people who already speak Welsh, and use its Vocab button to see the English for highlighted words. Look up only the words that block the meaning.

  6. Level 6

    I read at near-native level.

    Listen to Radio Cymru, and read BBC Cymru Fyw and Welsh novels for their own sake.

Move up a level when the current one starts to feel easy, and move back down if you lose the thread by the third line.

Try It on a Real Lesson

The lesson below comes from Bubblegum, where Poppy, your AI tutor, writes Welsh lessons at your level. You can read it here just as you would in the app. Read it at all three levels and notice which one you can follow while still looking up a few words.

Frequently Asked Questions About Comprehensible Input

Do I need to learn the mutations first?

No. You pick them up from short pairs that you hear again and again, such as gardd (garden) and yr ardd (the garden). A word like ardd is hard to look up because its first letter is gone, so use a dictionary such as the GPC Geiriadur app, which also searches for mutated forms.

Should I learn North or South Welsh first?

Learn the one spoken by the people you want to talk to. Some everyday words differ, such as rŵan in the north and nawr in the south for "now", and Bubblegum's lessons treat both as correct.

Is Bubblegum free?

Yes. The lesson library is free for everyone, because we believe everyone should be able to learn. It holds lessons that other learners asked Poppy for. A new custom lesson costs us real money to make, so you can ask Poppy for a free one, and Bubblegum Pro gives you unlimited custom lessons.

The Welsh lessons on this site are also free and need no account.
